speeicatia of Leiters Patent,

To all whom t may camera Be it known that I, ALFRED L. CoMTois, a

State of Massachusetts, have invented a new l and useful Strainer, ofwhich the following is a specitication.

The principal objects of this invention are to provide a new andimproved means for lconnecting the trame of a strainer with the Vstrainer itself; to provide a connection ot this kind ot such characterthat no solder will have to be used in mounting iton the strainer andthat its production will be materially simplified so that it can be madeit slides. It will be seen also that the cross chiey in dies.

l'The invention also involves other im-" provements and Jfeatures ofconstruction as will appear hereinafter. l

Reference is to be had to the accompanying drawings in which Figure 1 isa side view ot an extension strainer constructed in accordance withthisI invention. Fig. 2 is an end view of the same, andv F ig. 3 is aplan.

:The invention is shown as applied to lan ordinary extension consistingof two members 10 and 11 which` are connected by integral eyes 12at-their ends forming guides through which the iframes can slide uponeach other. It can be applied toother forms of frames however. Mountedon this frame is the strainer 14 which hasv an upper sheet metal band 15as usual. The upper band is provided with a top bead 16 integral withthe body of the band.

Just under the bead 16 is a wire frame 17 of a general circular formfitting the circumference of the band and resting just under the bead.In order to hold this wire in position without the employment of solier,the sheet metal band is provided with integral projections 18 extendingoutwardly just under the wire at intervals along'the length thereof. Thewire is formed of just such shape as to fit the band snugly and the titof these projections under it effectively holds it in position. This isan exceedingly simple way of securing this result and results inconsiderable' saving in expense as the parts can be made in dies. Intact it adds to the durability of the implement itself.-

with the extension or other frame this wire i'is provided with integralhooks at opposite sides thereof each hook comprising tivo parallelspaced outwardly extending arms 30. llach arm extends downwardly to forma vertical lmember 21 and these members can extend inwardly to formconnections 22 which are connected by an integral cross memberl 22%.This cross member 23 preferably henton the arc of a circle so as to titsnugly against the circumferential band 15 around the strainer.

Itwill be seen` that a space is provided between the circumferentialband and the outwardly extending arms through which the extension :tramepasses andfalong which bars fitting against the upper band as they do,serve to securely hold the parts in position and increase the rigidityand tirinnessof the Whole construction. At the same time no solder isrequired, although it solder is-applied the device willfbe furtherstrengthened. In this way there are no internal parts to project on theinside ot the strainer and no soldered pieces which are likely to becomeloose in use. The wire around the top of the strainer serves tostrengthen the strainer itself so that the upper metal band can be madeof thinner metal and an account of consisting of a single piece of wiresurrounding it and integral with the projections Yfor holding the frame,it is of exceedingly firm construction and inexpensive to make andwtoapply to the strainer.' On account ofthe form and features yabovedescribed the band 15 and connectedparts can bemade very rapidly anduniformly in dies.

Although I havt illustrated and described a preferred embodiment of theinvention, I' am aware that modifications can be made therein withoutdeparting from the spirit ot the invention as expressed in' the claims.Therefore,'l do not wish to be limited to all the features ofconstruction shown and described, but

llhat l do claim. is

1. As an article ot manufacture, a strainer comprising an extensiontrame and the strainer' having a wire extending around the upper partthereof and provided with integral projections forv receiving andguiding the extension frame. j

2. As an .article of manufacture, a strainer comprising an extensionframe .and a atented Felo-r 6., 1912K nppucaaamea october-9, 19111;seriai no; 653,534.1 f 1 I vstrainer having a pair of opposite guideslconnected therewith and i `of said cross piece and then upwardly subforthe extension frame, each of'said guides being formed of a piece of wirehaving two members spaced apart through which the rame passes, saidmembers being connected by an integral cross piece.

3. As, an article of manufacture, a strainer comprising a frame and astrainer having a pair of opposite guides for theframe, each of saidguides being formed ofla piece ofl wire havin 'two members spaced apartthrough which 'the frame passes, said members being connected by an'integral cross piece, said cross piece engaging the` wall of thestrainer and .conforming to the shape thereof.

4. As an article ofmanufacture, a strainer body having a top yband and awire member rovided with a cross piece below the top ot the strainer andengaging 'file 'out'eifwalll thereof, and two members extendingoutwardly from the ends stantially to the top of theA strainer and then`inwardly parallel with each other.

5. As an article of` manufacture, a strainer havlng a metal band and awire member provided withva cross piece below the top of the band andengaging the outer wall upwardly substantially to the top of the bandand then inwardly parallel with each j other, said members diver ingfrom each other and extending aroun the-band near the top and beingsecured thereto solely by contact with the band.

6. As an article Iof manufacture, a strainer having a top sheet metalband rovided with an outwardly extending bea at the top thereof, a wireextending substantially around the band just under said bead andprovided on opposite sides of the strainer with integral ways having apassage through' them adjacent to the wall of the strainer, thebandbeing provided with projections just under said wire to, hold it inplace.

7. As an article of-manufacture,` a strainer having an upper sheet metalband provided with an outwardly extending bead at ther top and a wireextending around the strainer 'itself under the bead, said sheet metalband .having extensions on the inside [formingl projections on theoutside -just under thewfire to hold it-in position against the bead.

In testimony whereof I have hereunto set my hand, in the presence of twosubscribing witnesses.
